    摘要: A slip control apparatus provides a smooth response of actual slippage amount during a transitional period when a lock-up clutch is shifting from a disengaged state to a slipping state, and quickly determines a response to external disturbances when the slipping of the clutch is in a steady state. The apparatus has a first control unit for outputting a first control value based on the difference between target slippage amount and actual slippage amount, a second control unit for outputting a second control value based on the actual slippage amount, and a clutch pressure regulating unit for controlling an electromagnetic valve to control a lockup system on the basis of the sum of the first and second control values. The first control unit performs control for the transitional state of the lock-up clutch between the disengaged state and the slipping state. The second control unit performs control in response to external disturbances when the slipping of the clutch has reached the steady state via the transitional state.

    摘要: The method of the present invention for producing β-chitin comprises a step of cultivating an alga capable of producing β-chitin using a medium that contains nitrogen (N), phosphorus (P), silicon (Si), and selenium (Se), wherein the weight ratio of phosphorus to nitrogen (P/N) is 0.1 or above, the weight ratio of silicon to nitrogen (Si/N) is 0.1 or above, and nitrogen (N) is contained at 160 ppm or more. It is preferable that selenium (Se) is present in the medium at a concentration of 0.08 ppm to 0.008 ppb.
